最近,美国农业部已授予新泽西州DNA植物技术公司培育的遗传品质优异的蕃茄以植物品种保护法(PVPA)证书,这是通过体细胞克隆变异法培育的蔬菜新品种。在大田试验中,这种蕃茄的固体含量比其他市售品种高20％;蕃茄的固体成份增加可降低食品加工厂的原料成本。用于培育这种优质蕃茄的技术——体细胞克隆变异法揭示了植物自然遗传的可变性。这种 Recently, the U.S. Department of Agriculture has granted the New Jersey Plant Phytosanitary College with the certificate of Plant Variety Protection Act (PVPA), a genetically superior tomato cultivar based on somatic clonal variation. In field trials, the tomatoes contain 20% more solids than other commercially available varieties; the increased solid content of tomatoes reduces the cost of raw materials for food processing plants. The technique used to cultivate this quality tomato - the somaclonal variation method reveals the variability of the plant’s natural heredity. This
